Gain-intensified slot antennas backed by SIW cavity using… Gain-Enhanced SIW Cavity-Backed Slot Antenna with Arbitrary Levels of Inclined Polarization.In this paper, a gain-increased method of cavity-backed slot antennas based on excitation of high-order substrate-integrated waveguide cavity resonance has been proposed. High Gain Compact Strip and Slot UWB Sinuous Antennas...… Three ground-backed compact strip-and slot-sinuous antennas are analyzed. Proposed configuration allows for a single lobe, polarization-versatile, high efficiency, and ultrawide band antenna not needing a cumbersome lossy back cavity typical of conventional single-lobe sinuous antennas. Simulated gain patterns of the SIW cavity-backed slot … High-gain antennas have various applications such as in satellite platforms, radar systems, routers, and repeater systems.In this paper, we propose a novel enhanced-gain planar slot antenna backed by an SIW cavity for 2.4 GHz wireless local area network (WLAN) applications.

Background High gain omni-directional antennas are more difficult to realize with horizontal polarization. Vertical radiating elements stacked along a vertical line provide a natural means of achieving high gain with vertical polarization. Radiating elements are often λ/2 or near λ/2. A Directive Ultra Wideband Sinuous Slot Antenna In this paper, a directive sinuous slot antenna for Ultra Wideband (UWB) applications is presented. This antenna is feeding by a microstrip taper balun, which can be used as a coaxial line to Lecher line transition. To obtain directive antenna a reflector has been added and optimized. Understanding antenna gain – RCExplorer A common misprecepion is that a higher gain antenna is simply more effective than a low gain one; this is not true. First of we need to understand what the dBi value of an antenna means: “The decibel (dB) is a logarithmic unit of measurement that expresses the magnitude of a physical quantity (usually... 10 Best High Gain Antennas For WiFi Router | Wonderful…
